Hello Christopher (@ctrav)
I used code snippets for Facebook, Google+, Twitter, Tumblr, E-mail and Pinterest sharing in one of my clients site. All options were checked and work well.
First of all, I used method that Waldo showed in this post FREEBIE: Sharing is Caring :) - Show & Tell - Forum | Webflow
Then I just found and adjust code snippets for Social Networks that I needed
Facebook
<a class="w-inline-block social-share-btn fb" href="https://www.facebook.com/sharer/sharer.php?u=&t=" title="Share on Facebook" target="_blank" onclick="window.open('https://www.facebook.com/sharer/sharer.php?u=' + encodeURIComponent(document.URL) + '&t=' + encodeURIComponent(document.URL)); return false;"></a>
Twitter
<a class="w-inline-block social-share-btn tw" href="https://twitter.com/intent/tweet?" target="_blank" title="Tweet" onclick="window.open('https://twitter.com/intent/tweet?text=%20Here goes text of your tweet ' + encodeURIComponent(document.title) + ':%20 ' + encodeURIComponent(document.URL)); return false;"></a>
Google+
<a class="w-inline-block social-share-btn gplus" href="https://plus.google.com/share?url=" target="_blank" title="Share on Google+" onclick="window.open('https://plus.google.com/share?url=' + encodeURIComponent(document.URL)); return false;">
Pinterest
<a class="w-inline-block social-share-btn pin" title="Pin it" target="_blank" href='javascript:void((function()%7Bvar%20e=document.createElement('script');
e.setAttribute('type','text/javascript');
e.setAttribute('charset','UTF-8');
e.setAttribute('src','
http://assets.pinterest.com/js/pinmarklet.js?r='+Math.random()*99999999);document.body.appendChild(e)%7D)());'></a>
With Pinterest sharing, it will take Meta description from the current page and show all images from the site. But it is possible to adjust by changing settings (look Pinterest docs)
Tumblr
<a class="w-inline-block social-share-btn tmb" href="http://www.tumblr.com/share?v=3&u=&t=&s=" target="_blank" title="Post to Tumblr" onclick="window.open('http://www.tumblr.com/share?v=3&u=' + encodeURIComponent(document.URL) + '&t=' + encodeURIComponent(document.title)); return false;"></a>
E-mail
<a class="w-inline-block social-share-btn email" href="mailto:?subject=&body=:%20" target="_blank" title="Email" onclick="window.open('mailto:?subject=' + encodeURIComponent(document.title) + '&body=' + encodeURIComponent(document.URL)); return false;"></a>
These code snippets will take information from current page meta image and meta description. And, as you know, on the dynamic pages template you can set these settings dynamically too (page settings above the custom code areas).
Classes of anchors may be different (depend on what you will use on 1st step) but “w-inline-block” is necessary.
Hope it helps.
Cheers,
Anna
